I've been pretty involved with watch the series advertisements and production develop, and I really don't think that the pilot is going to be representory of the show. Aside from the good points above, they needed to introduce a ton of characters (and that's just going to get worse.) I think they did pretty good with what they had, at the moment - part of the joy of this series is watching the characters really develop, and I think it's going to be the same with the series.
As far as finding the wolves go, you're right that that was a bit far from the books. But it's more the tone, than anything else. GRRM himself admitted that he's gotten letters from fans saying "That horse should be black," and he just had to say that it didn't really matter to him. It's about the setting and the themes - and HBO have shown that they may be capable of portraying those well. The detail was certainly breathtaking.
Anyway. looking forward to next week.
